Problem number 15. This card is lying on the table. It is flipped over its top edge, then flipped over its left edge, as shown in the picture.  What does the card look like after two flips? To solve this problem, we are going to have to make a mirror image in our minds.  First over the top of that line, and then over the other line. The first flip causes the triangle to be on the same side, but upside down. The square in the same spot.  And the circle in the same spot.  And then we flip it over again. So the circle would be in the spot the triangle was before. Then the square stays in the middle.  And then on the other end, the triangle is still upside down. So it doesn't look like A, it doesn't look like B, but it does look like B. So B is our answer.

Video Summary

The problem involves flipping a card twice and determining its final appearance. After the first flip over the top edge, the triangle is upside down but remains on the same side, while the square and circle stay put. The second flip over the left edge moves the circle to the triangle's initial position, leaving the square in the middle, and the triangle remains upside down at the opposite end. The final configuration matches option B. Therefore, option B is the correct answer for the card's appearance after the two flips.
